No, the it won't be. Coiling it up retains the electrical tuning length, but the gain of the antenna is seriously reduced.
Think of it this way....a weak electromagnetic field is directed from the transmitter to the reciever. The small coil of wire won't see much of this signal compared to being help upright in an antenna tube. Sort of like pulling a net up through a school of fish.....bigger net = more fish.
What I've seen the airplane guys do, is coil up the excess wire inside the airplane....."after" they've strung the wire from where it exits the fuselage to the top of the rudder. Same thing in most of my vehicles....some excess wire is coiled up in the electronics box. But the more coiled up, the weaker the signal getting into the receiver.
If you run a small scale vehicle where you control it in very close proximity, you can coil all your antenna wire up inside the car. Just do a range check first to be sure you still have control at the max distance you will be away from the vehicle.
